DERAILING DEVICE.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed July 24, 1913. Serial No. 781,011.

To all whom it may concern:

Be it known that I, EDWARD ROCK, a citizen of the United States, residing at Laurel, in the county of Jones, State of Mississippi, have invented certain new and useful Improvements in Derailing Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in derailing devices for cars and more particularly for derailing logging cars.

The invention has for its object to so construct a device of this character that the same can be easily and quickly applied to the outer rail of the railway track so that an oncoming car will be derailed upon engaging the device.

With this and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the device showing it in place upon a rail. Fig. 2 is a side elevation of the device. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 4 is a similar view on line H of Fig. 2.

Referring to the drawing, the numeral 1 designates the base of the device, which has one of its ends inclined, as at 2, so that when said base is engaged upon the head of the rail, the tread of the wheel may ride upon it and upon the adjacent end of the base 1.

The other end of the base 1 is beveled, as at 3, said bevel extending the full width of said base, and has formed integral therewith a vertical flange 4, which also extends the full width of the base 1 and is disposed in diagonal relation thereto, one end of said flange terminating in a vertical side flange 5 which has one of its ends terminating in an outwardly inclined wing 6, it belng of course understood that the flange 5 is formed integral with the base 1.

Formed integral with the other side edge of the base 1 are depending plates 7 which have their lower ends provided with shoulders 8 which are designed to engage under the head of the rail, and serve in conjunction with the plate 9 to prevent lateral displacement of the device.

The plate 9 is provided with a slot 10 which serves as a hand-hold so that the device may be carried conveniently.

Formed between the inner end of the wing 6 and base 1 is an inclined surface 11 which is engaged by the flange of the wheel after the tread thereof has passed over the inclined end of the base, whereupon the wheel flange will pass upon the base 1, and will be deflected sidewise upon coming in contact with the diagonally disposed flange 4, thus derailing the car.

It is obvious that the device may be used with equal success for derailing passenger trains in case the crew of an oncoming train disregards the danger signal.

What is claimed is .A derailing device comprising a base having an upwardly extending vertical flange formed upon one of its side edges, a flange extending diagonally across the end of the base, a flange extending outwardly from and inclined with respect to the base member between its ends, an inclined surface formed between the base and wing for engagement by the flange of the wheel to guide the same upon the base for contact with the diagonally disposed flange, and plates carried by the base for preventing the lateral displacement of the device from the rail.

In testimony whereof, I aflix my signature, in the presence of two witnesses.

EDWARD ROCK.
